CLOTH-GUIDING DEVICE FOR TEXTILE-MACHINES.-

Application filed February '7, 1918.

To all whom it may concern:

Be it known that I, GEORGE BARTON, a citizen of the United States, andresident of ltasthampton, county of Hampden, and State of Massachusetts,have invented an Improvement in Cloth-Guiding Devices forTextile-Machines, of which the following is a specification.

My invention has for an object the guiding of cloth to textile machineswhich are intended to manipulate and stretch the cloth such as isaccomplished in tentering machines, by way of example, whereby the clothis properly delivered to the cloth clamps on the machine in an effectiveand positive manner to insure the desired action while in the custody ofthe tentering machine.

Heretofore in practice considerable difficulty has been found inattempts to feed the selvages of a fabric to the cloth clamps of thereciprocating frames of a tentering machine, in that the said frames areso supported that during their reciprocation they alternately approachand recede from each other, varying the transverse width apart of thetwo chains of cloth clamps. It is therefore the object of my inventionto provide an effective feeding mechanism for the cloth which shallimpart to it transverse oscillations commensurate with thereciprocations of the tentering frames and which shall maintain the selrages in proper alinement with the cloth clamps of the respectiveframes.

My object is further to provide automatic means foracting upon theselvages of the fabric and controlled by the lateral positions of theselvage edges to cause the cloth to be more or less stretched as towidth and positioned transversely, whereby it is accurately guided intothe cloth clamps at each side of the machine, with the result that thesaid clamps shall grip the fabric adjacent to the selvages thereof withaccuracy for the better manipulation of the fabric during its stretchingand working While-beiug conveyed along the length of the tenteringmachine.

My invention also consists of improvements hereinafter described wherebythe. above objects and results are attained, said improvementscomprising certain organization and combination of parts which areSpecification of Letters Patent.

Serial No. 215,818.

fully described hereinafter and more particularly defined in the claims.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings the embodiment thereof which is at presentpreferred by me, since the same is in form to give satisfactory andreliable results, but it is to be understood that the severalinstrumentalities of which my invention consists, can be variouslyarranged and organizedand that my invention is not limited to theprecise arrangement and organization of the instrumentalities hereinshown and described.

Referring to the drawings :Fig. l is a plan view showing my improvedcloth guiding means as applied to the receiving end of a tenteringmachine; Fig. 2 is a side elevation of the same; Fig. 3 is an elevation,with part in section, showing a portion of my improved guiding means ona larger scale; Fig. at is a front elevation of the same; and Fig. 5 isa plan view of the construction shown in Fig. 4.

2, :2, illustrate the receiving ends of the longitudinal frames of atentering machine. These frames are supported at numerous places alongtheir length by means of horizontal frames 8 journaled at their centers4; upon suitable standards 4? and having their outer ends journaled at 3to the under side of the frames 2, 2, whereby the said frames aresupported and permitted to have longitudinal reciprocationsimultaneously in opposite directions. The oscillation of the supportingframes 3 causes the longitudinal frames 2, 2, not only to reciprocate inopposite directions, but to approach and recede from each otheralternately during such longitudinal reciprocations, all of which iswell known in connection with tentering machines. Tentering machines arecommonly provided with a transverse screw shaft 5 which permits relativeadjustment of the frames 2, 2, toward or from each other to suit fabricsof different widths, but such provision need not be specially consideredas this is a common expedient in tentering machines. 6 representschains, and 7 cloth clamps formed thereon. Ordinarily, each link of thechain is provided with a cloth clamp so that these chains in realityconstitute chains of cloth clamps, and they are guided longitudinallyalong the frames 2 and about the guide wheels 6* at the receiving end ofthe tentering machine. Suitable means is also provided at this end forputting the chains under tension but such details need not be consideredas it is a usual construction of tentering machines. While the clothclamps are conveyed around the guide Wheels 6 the gripping jaws of theclamps are automatically opened by contact with the rim of the wheel 7which is supported andjournaled concentrically with the aXis of theguide Wheels 6". In this manner the cloth clamps are openedautomaticially at. the receiving end of the .tentering frames so as toreceive the selvages of the fabric and immediately thereafter grip them.I will'novv proceed to describe in detail my improvements which areapplied to the receiving ends of the reciprocating frames 2, 2, of thetentering machine.

To the end of each of the reciprocating frames 2, 2, I secure a bracket8 which is provided with vertical bearings 9, 9, in which avertic'alshaft 20 is journaled. Secured rigidly to the top of the shaft 20 is ahorizontal bearing 11, and similarly secured to the extreme bottom ofthe shaft 20 is a horizontal bearing 12. The bearings 11 and 12 areparallel. There are similar vertical shafts 2'0 and bearings.1l and 12in connection with the'bracke'ts 8 of each of the tentering frames. 13is a horizontal shaft which 'e'Xtends through the bearings 11 at eac'hside of the machine, and at one side the shaftis held againstlongitudinal adjustment by collars 14 on the opposite sides ofrthebearing 11, said collars being secured inposition "by being pinned tothe shaft (Fig. The other end of the shaft loosely extends through thebearing 11 of the other tenterin'g frame. Parallel to the shaft 13 andjourn'aled in the bearings 12 at each side of the machine, is a secondshaft 15, and similarly this shaft is held against longitudinal movementby similar collars 1e pinned to it and arranged upon each side of one ofthe bearings12. The other end of the shaft 15 is loosely held in theother bearing 12 as in the 'case of the shaft 13.

sated fer the shafts 13 and 15 sliding longitudinally through-one set ofthe bearingsil and 12,as will be more clearly understood by examinationof Fig. 1. The shafts 13 and may be free to rotate but this is notessential, as they may be simply smooth guides over which the cloth isguided as in di'c'ated, ,It will be noted that when the 'oscillations ofthe shafts 13, and 15 take place, they will-necessarily rockthe verticalshafts 20, and this rocking of the vertical shafts provides means forrocking the guider devices which position the selvagcs eorrectly toinsure their being properly re ceived by the cloth clamps.

I will now describe the cloth feeders which definitely position thefabric so that the lateral or selvage edges thereof are accuratelydelivered to the cloth clamps. Each of the vertical shafts 20 isprovided with a guider 19, and these latter project inwardly toward thecloth in opposite directions, but in all material respects theirrelation to and action upon the cloth is the same, and it will sufficeto describe in detail one of these devices. Secured to the shaft 20between the two bearings 9, 9, of the bracket, is a. sleeve 16 fastenedin position upon the shaft by means of set screws 17. This sleeve 16 isprovided with a. horizontal hub 16 through which a horizontal adjustablerod 21 extends, said shaft being adapted to be socured in adjustedposition by means of the set screw 22. The end of the rod 21 adjacent tothe cloth has hinged to it at 24 the guider frame 23 so that this framemay be adjusted in a vertical plane, and at the same time may beadjusted transversely of the cloth by the longitudinal adjustment of therod 21. mechanism for the guider frame gives capacity for universaladjustment. The guider frame 23 is provided. with the two guide surfaces25 over which the cloth travels. Journaled to the guider frame 23 infront of these guide surfaces 25 is a roller 26 between which and theguide surfaces the fabric passes. 27 is a guider roller which is movableto or from the roller 26, and is arranged upon the opposite side of thefabric so that the fabric is pinched between the two rollers when theroller 27 is moved toward the roller 26. The roller 27 is journaled in ahinged frame 28 carried by the guider frame, and this frame is operatedby a suitable motor device 28 controlled by a valve 29 operated by asuitable trip device 30 which provides an arm 30 which extends upwardthrough a slot in the guider plate 25 in position to be acted upon bythe selvage of the cloth. In operation, the motor device is actuated bycompressed air to move the roller 27 toward the roller 26, and the timeof action of this motor devicc is regulated by the valve under thecontrol of the fabric. It Will further be observed that the guider frameis adjusted obliquely to the rod 2] so that the rollers 26 and 27 arearranged at an oblique angle, such that when the fabric is pinchedbetween the two rollers 26 and 27, its upward movement will tend toshift the fabric laterally toward the control arm or finger 30 andtoward the cloth clamps. The fabric in traveling upward is caused to actupon the controlling finger 30 and when It is manifest that thisadjustable llll the same is moved to the left (Fig. 1), the air pressureis exhausted from the motor to relieve the pressure from the roller 27to arrest further lateral movement of the eel vage of the fabric. Shouldthe selvage tend to move to the right (Fig. 4:), it will be followed bythe finger 30, and this will, through the valve, supply pressure to themotor and cause the roller 27 to apply pressure to the fabric andthereupon through the oblique arrangement of the rollers, the selvage ofthe fabric will tend to once more move to the left. In this manner, theselvage is guided accurately between very slight variations into thecloth clamps 7 of the tenter frame so that it is properly gripped bysaid clamps. The particular details of the motor devices for operatingthe guiders are immaterial to the present invention, but the preferredconstruction which is employed by me is that which is shown in thepatent granted to H. C. Brehmer on December 8, 1914-, and numbered1,120,019,

It will be understood that the guiders operate on each selvage of thefabric in an independent manner, but the totalwidth of the fabric whenin a reasonably stretched condition should just equal the normaldistance between the two control fingers 30 of the feeders, andthereafter the fabric might be considered as shifting bodily slightlyfrom one side or'the other, or stretched by action t one selvage or theother, so as to aroperly be fed to both sets of cloth clamps on thetwotenter frames. Even if the cloth, passing over the guide shafts 13and 15, should be more or less loose as to width, the guiders 19 willaccurately control the selvages into proper alinement with the clothclamps, and it will therefore be seen that each guider 19 directlycooperates with its particular associated cloth clamps and tenter framefor laterally positioning the cloth selvage, but both of the guidcrs 19and the oscillating rods 13 and 15 cooperate in conjunction with takingcare of the fabric being fed to the tenter machine and causing it tooscillate in conformity with the oscillations produced upon the fabricin the custodyof the cloth clamps of the tenter machine itself, wherebyat all times the fabric is properly fed to the machine and withoutputting any undue strain upon it at its point of delivery into the clothclamps. After it has once been gripped by the cloth clamps, the fabricmay then be subjected to the various complex stretching operations whichare insured by the action of the tenter machine.

I have found it desirable that two transverse guide shafts 13 and 15 beemployed, one above and the other below the guiders 19, but I do notrestrict myself to the use of the lower shaft 15 as this shaft maybeomitted if the cloth is properly guided from near the floor.Furthermore, it is to be under- &

stood that while it is desirable to feed the cloth upward so that thenormal. gravity action of the cloth below the guiders may be utilized, Ido not limit myself to this particular arrangement as the parts may besuitably arranged to permit the cloth to be delivered to the transverseguide shaft 13 from the direction found most convenient and suitable.The more essential feature of my invention when applied to ten teringmachines, resides in the oscillating shaft 123 moved under the action ofthe reciprozating tenter frames, and combined with mechanism foroscillating feeders in conjunction with the shaft, but it is to beunderstood that my improvements are not restricted to the particularcharacter of the machine to treat the fabric after the cloth has beenonce delivered to the cloth clamps.

It will now be apparent that I have devised a novel and usefulconstruction which embodies the features of advantage enumerated asdesirable, and while I have in the present instance shown and describedthe preferred embodiment thereof which has been found in practice togive satisfactory and reliable results, it is to be understood that I donot restrict myself to the details, as the same are susceptible ofmodification in various particulars without departing from the spirit orscope of the invention.
